Theory C: She Wanted to Focus on Her Career

With her flower crowns and love for scrunchies, Cressida has been described as a independent woman who was having trouble deciding between her career and joining the royal family. Perhaps the taste of royal life helped her make up her mind. The Daily Beast reported on the idea:

"It should be noted that friends have previously said that for all the speculation in the press about whether or not she and Harry would announce their engagement this year, Cressida had no plans and no desire to get married at such a young age. She was said to be wrestling with the knowledge that she would have to choose between a career as an actor and dancer or life in the royal family."
